Apparently, robot designers are worried that they're not creating automatons that are creepy enough, because a team of engineers at Virgina Tech have put something together that will give even the toughest of men chills. The robot in question is the three-legged STriDER (Self-excited Tripedal Dynamic Experimental Robot, not to be confused with CMU's Strider) which balances itself on two legs and then flips its body 180-degrees, bringing its third leg forward with the motion. According to project leader Dennis Hong, "STriDER's gait is closer to that of a human walking than most bipedal humanoid robots you see today," adding, "This is how we humans walk, we do not actively control our knees, we just let them swing." It does seem to be true, as the robot has an eerily life-like quality to its movements. Don't believe us? Take a look at the video after the break and see the tripod in action.
